Which is bigger — Canada or China? Argentina or Kazakhstan? The Largest Countries by Area Quiz tests how well you really know the size of the world’s nations. Play a quick Bigger or Smaller face-off, pick the biggest of four, or hunt down the world’s giant countries on an interactive map. It runs right here in your browser, free, with no sign-up.
Russia is the largest country on Earth at over 17 million km² — bigger than the next two countries combined — while just six nations cover roughly 40% of all land. This quiz turns those facts into a game: five modes, a streak multiplier, a Speed Round against the clock, and a review of every match-up you missed. A local leaderboard remembers your best runs.
It is part of our growing set of geography quizzes — the same fast, modern engine behind the Countries of the World Quiz, World Capitals Quiz, and Landlocked Countries Quiz. Scroll down for the ten largest countries by area and answers to common questions.

How to play
- Bigger or Smaller — two countries appear side by side. Tap the one with the larger area. Every match-up has a clear winner, so it is all about your instinct for scale.
- Which is Largest? — four countries, one is the biggest by area. Pick it. The decoys are always smaller, but often close enough to make you think.
- Locate the Giants — a top-40 country is named with its size rank. Find it and tap it on the world map.
- Speed Run — rapid-fire Bigger or Smaller against the clock. Build a streak to multiply your score.
- Daily Challenge — six comparisons that are the same for everyone in the world that day. Finish it to keep your daily streak alive and share your result as an emoji grid.

The 10 largest countries by area
“Largest” here means total area — land plus inland water — for sovereign countries, the same basis used by the United Nations and standard reference lists. (Greenland and Antarctica are not independent countries, so they are not ranked.) These ten giants alone account for roughly half of all the land on Earth:
- Russia — 17,098,242 km²
- Canada — 9,984,670 km²
- China — 9,706,961 km²
- United States — 9,372,610 km²
- Brazil — 8,515,767 km²
- Australia — 7,692,024 km²
- India — 3,287,590 km²
- Argentina — 2,780,400 km²
- Kazakhstan — 2,724,900 km² (the largest landlocked country)
- Algeria — 2,381,741 km² (the largest country in Africa)
A few tips for the quiz: do not trust population as a guide to size — India is far more populous than Canada yet only a third of its area, and tiny Bangladesh has more people than huge Russia. Watch out for countries that “feel” small on a Mercator world map but are not, like Algeria, Kazakhstan, and Argentina, and for the way the same projection makes Canada and Russia look even more enormous than they are.
Data & method
Country areas come from the open mledoze/countries dataset (ODbL licence). The interactive world map is built from Natural Earth via the world-atlas TopoJSON (public domain). All of the data is bundled into the quiz at build time, so it loads instantly and needs no third-party connection while you play. The ranking covers the world’s independent countries by total area.

Frequently asked questions
What is the largest country by area?
Russia is the largest country in the world by area at 17,098,242 km². It is almost twice the size of the second-largest country, Canada, and on its own covers about 11% of all the land on Earth, spanning eleven time zones across Europe and Asia.
What are the 10 largest countries in the world?
In order of total area: Russia, Canada, China, the United States, Brazil, Australia, India, Argentina, Kazakhstan, and Algeria. The first six are all over 7 million km²; together the top ten hold roughly half of the world’s land area.
Is “largest” measured by area or population?
This quiz ranks countries by area — total land plus inland water. That is different from population: China and India are the most populous countries, but by area China is third and India is seventh. Canada and Australia are enormous in area yet have relatively small populations.
Is the quiz free, and does it work on mobile?
Yes to both. It is completely free with no sign-up, and it is built mobile-first — the comparison cards, answer buttons, and world map all scale to a phone screen with finger-sized tap targets. Your scores and daily streak are saved on your own device.
Where does the data come from?
Country area figures come from the open mledoze/countries dataset (ODbL licence), and the world map is built from Natural Earth via the world-atlas TopoJSON (public domain). The data is bundled into the quiz, so it loads instantly and works without any third-party connection.
